【摘要】 目的 :探讨螺旋CT门静脉血管造影 (SCTP)及三维重建对肝炎后肝硬化门静脉高压的诊断和临床应用价值。方法 :5 7例肝炎后肝硬化患者行SCTP及三维重建。三维重建方法包括最大强度投影 (MIP) ,表面阴影成像 (SSD)和多平面重建 (MPR)。结果 :MIP和SSD显示 5 1例门静脉 1～ 2级分支增粗 ,肝内门静脉 2级以下分支细小、扭曲 ,3 5例呈枯枝或残根状。 6例仅见门静脉 1～ 2级分支增粗 ,肝内门静脉 2级以下分支未见显影。侧支循环血管开放表现为食管下段静脉曲张 (n =2 1) ,食管周围静脉曲张 (n =14 ) ,胃周静脉曲张 (n =2 4) ,脐静脉曲张 (n =11)及腹膜后静脉曲张 (n =9)。结论 :SCTP是诊断和评价肝炎后肝硬化门静脉高压有效方法 ,对门静脉高压程度 ,上消化道出血预测及门静脉高压术前评估有较大价值。更多还原

【Abstract】 Objective:To assess the application of spiral CT portography (SCTP) in diagnosis of portal hyertension in postheratitis cirrhosis.Methods:57 cases of hepatitis cirrhosis were performed SCTP.MIP,SSD and MPR were used as three dimensional models.Results:MIP and SSD demonstrated dilatation of portal branches of 1～2 orders and thinning and distortion of smaller branches below 1～2 orders (n=51),“withered tree” or “stump” appearance in 35 cases of portal branches (n=35);smaller branches of portal vein could not be demonstrated (n=6).The collaterals including esophageal varices (n=21),paraesophageal varices (n=14),paragastric varices (n=24),recanalized paraumbilical vein (n=11) ,and retroperitoneal varices (n=9) could be well shown.Conclusion:SCTP is an effective method in diagnosis of portal hypertension and collaterals in postheratitis and also has an important value in evaluation of the degree of portal hypertension and for planning of surgical treatment.更多还原
